Examples of the solid electrolyte of the partition are thorium oxide or stabilized zirconium oxide for use with oxygen, a silver halide for use with halogens, and silver sulphide for use with sulphur. As shown, the resistor 6 is purely metallic, and in alternatives may be a semiconductor element, e.g. n-silicon carbide, in which case a fixed resistor 7 is also provided, or a negative temperature coefficient resistance in which case it is connected in parallel with the ammeter 5, the resistor 7 being connected in series with the ammeter 5.

Abstract: 1318205 Thermoelectric devices UNITED KINGDOM ATOMIC ENERGY AUTHORITY 19 April 1971 [30 Jan 1970] 4730/70 Heading H1K A thermoelectric generator and a heat source are mounted within an enclosure from which they are thermally insulated by a filling of xenon gas. Xenon has a low thermal conductivity and also suppresses the thermal conductivity of gases released into the housing from the surfaces of the generator components. The generator may comprise a radio isotope heated thermoelectric block mounted inside a stainless steel housing having an opening at one end by means of which the housing is evacuated and filled with Xe. The opening is then closed by a plug which is welded to the housing. Alternatively a Cu tube brazed into the opening can be used to evacuate and fill the housing and is then sealed by crimping the tube to form a cold weld. The pressure of the Xe filling is preferably slightly lower than atmospheric pressure so that leaks can be detected due to the increase in thermal conductivity resulting from air entering the housing.

Abstract: 1335737 Helicopters WESTLAND AIRCRAFT Ltd 29 Feb 1972 [4 March 1971] 5986/71 Heading B7N [Also in Division B8] A winch mechanism for raising and lowering a sonar body 15 on a cable 16 through an aperture in the floor 12 of a helicopter 11, comprises a head assembly 22 from which the cable 16 depends and which is movable between an upper stowed position and a lower operational position adjacent the floor 12. The head assembly 22, comprising rollers for the cable, an emergency cable cutting device and a cable angle sensor coupled with the helicopter controls, is freely pivoted between a pair of beams 20, between which the winch drum 18 is mounted. The beams 20, each having two arms, are freely pivoted on the winch drum shaft 27 and a rod 24 pivoted to the head 22 and the drum mounting frame 19 controls the attitude of the head 22 during rotation of the beams 20 between the upper and lower positions. A cable laying device 21 is pivoted to the other arms of the beams 20. Initial rotation of the drum 18 to lower the body 15 causes anticlockwise rotation of the beams 20 until they latch on to the frame 19 at 26 having moved the head 22 into its lowered position, the head 22 being unlatched and raised during winding in of the cable 16, by the body 15 abutting the head 22. The drum drive motor is mounted inside the winch drum. A drip tray 29 under the winch drum deflects water to the floor aperture which includes a conical guide 13 from the body 15. In the embodiment of Fig. 3 and 4 (not shown) the head assembly and the layering device are mounted in a casing which in the lowered operational position seals the interior of the helicopter from the floor aperture and is received inside another housing in its upper stowed position.

Title: Telephone subscribers instruments
IPC: H04M1/31
Filed: 1972-02-17
Abstract: 1347929 Impulse transmitters STANDARD TELEPHONES & CABLES Ltd 17 Feb 1972 7315/72 Heading H4K In an impulse transmitter a semi-conductor device is connected in series in a loop with a telephone line and is switched between a high and low impedance state under the control of a pulse waveform whereby the loop is effectively opened and closed to perform impulse transmission over the telephone line. More particularly the semi-conductor device is a transistor which replaces the line relay contacts in a subscriber station. The pulse waveform may be derived from a pulse waveform generator and the dialling information for controlling this generator may be derived using push-buttons, cord or repertory selective signalling. Several digits may be stored in a data store, the contents of the store controlling the waveform generator. The pulse waveform may be associated with data transmission. Transistors also replace the off-normal contacts of the subscriber station for muting the speech circuits during impulsing. The station may have a local battery which is charged over the telephone line when the subscriber is off-hook except during impulsing. The circuit comprises an impulsing transistor TR1, off-normal transistors TR2, TR3, speech transmission circuit 11 and a battery charging circuit 12. A diode bridge 15 is connected to the line 10 to render the circuitry immune to polarity reversals on the line and a voltage limiting device 16, e.g. a Zener diode or a non-linear resistor, is used to protect the transistors against over voltages on the line. When the impulse transmitter is operative the charging circuit 12 is arranged together with the speech transmission circuit 11 to drop the telephone line voltage to the level required to hold the transistor TR1 on i.e. the line looped. When the transistor TR1 is turned off by the application, by means not shown, of a pulse to its base, logic circuitry causes transistors TR2, TR3 to be turned on thereby disabling the speech transmission circuits and muting the receiving transducer 14. The transistor TR1 may be suitably replaced by a thyristor, a triac, or a semi-conductor gate controlled switch. The receiver muting transistor TR3 may also be arranged in series with the receiving transducer 14 in which case it would be turned off during impulse transmission; this transistor could be replaced by either an N- channel insulated-gate enhancement, or an N- channel junction-gate, FET. In an arrangement where the local battery is charged with the subscriber on-hook or where it is charged from an external source, alternative means, not disclosed, must be used in place of the battery charging circuit to drop the line potential to that required to hold transistor TR1 on.
